Description
Concept of correlation versus causation
Create a data set with 10 or more data pairs and create a scatter plot to analyze.
Remember, your data set needs to include two quantitative variables. If you create your own, be sure to use a minimum of 10 data pairs. Be certain that when you create your own data, you share what you chose as your variables, your quantitative data, and where you found the data.
After creating your scatterplot, respond to these questions:
First, state the variables and list all the data elements you used to create your scatter plot. Your classmates will need this information to complete post 2.
Next, calculate the correlation coefficient (r-value). State that value in your response.
Based on the visual display of the scatterplot, describe the trend you notice. You should include such comments as to whether it appears linear, the direction the trend is going, and the strength of the trend.
Finally, explain why you think the correlation coefficient (r-value) supports your description of the data trend.
